Safety Data Sheet (SDS) for Glacial Acetic Acid

Introduction to Glacial Acetic Acid

Glacial acetic acid is a colorless, liquid organic compound with a pungent, vinegar-like odor. It is a highly concentrated form of acetic acid, containing approximately 99-100% acetic acid by weight. Commonly used in various industrial applications, glacial acetic acid serves as a key raw material in the production of acetic anhydride, acetate esters, and various other chemical compounds. Given its role in different chemical processes, understanding the safety and handling of glacial acetic acid is essential.

Chemical Identification

- Chemical Name Acetic acid - CAS Number 64-19-7 - Synonyms Ethanoic acid, methane carboxylic acid - Molecular Formula C2H4O2 - Appearance Colorless liquid

Hazard Identification

Glacial acetic acid is classified as a hazardous substance under various global regulatory frameworks. The primary hazards associated with glacial acetic acid include

- Corrosive It can cause severe skin burns and eye damage upon contact. - Flammable It has a flash point of 39°C (102°F), making it a fire hazard when exposed to strong oxidizers or heat sources. - Health Risk Inhalation of vapors can lead to respiratory distress, and ingesting it can cause severe internal injury.

To ensure safe handling and use, the following precautions should be taken

1. Personal Protective Equipment (PPE) - Wear appropriate protective clothing, gloves, and safety goggles. - Ensure the use of respiratory protection when adequate ventilation cannot be ensured.

2. Storage - Store in a cool, well-ventilated area away from heat sources and incompatible materials (such as strong oxidizers). - Use corrosion-resistant containers for storage.

3. Handling - Minimize exposure by working with glacial acetic acid in a fume hood or well-ventilated area. - Avoid direct contact with skin and eyes.

First Aid Measures

In the case of exposure to glacial acetic acid, immediate first-aid actions are crucial

- Skin Contact Remove contaminated clothing and rinse skin immediately with plenty of water for at least 15 minutes. Seek medical attention if irritation persists. - Eye Contact Rinse cautiously with water while holding the eyelids open for at least 15 minutes. Get medical attention immediately. - Inhalation Move to fresh air immediately. If breathing is difficult, provide artificial respiration and seek medical help. - Ingestion Do not induce vomiting. Rinse mouth, and seek immediate medical attention.

Firefighting Measures

In the event of a fire involving glacial acetic acid, the following measures should be taken

- Extinguishing Media Use dry chemical, foam, or carbon dioxide extinguishers. Avoid water as it can react with the acid and cause splattering. - Special Hazards Fire may produce hazardous fumes. Wear self-contained breathing apparatus (SCBA) when fighting fires.

Environmental Considerations

Glacial acetic acid can pose various environmental hazards. In case of a spill, it is crucial to

- Contain the spill using appropriate absorbed materials (e.g., sand or vermiculite). - Prevent the chemical from entering waterways by blocking drains and taking measures to contain runoff. - Dispose of the neutralized waste according to local regulations.

Conclusion

Understanding glacial acetic acid’s safety data is vital for any personnel working with this chemical. Proper safety measures, storage, handling guidelines, and emergency procedures are essential to minimize the risks associated with its use. Always refer to the specific Safety Data Sheet (SDS) of glacial acetic acid from suppliers for detailed information on handling, first aid, and fire safety to ensure a safe working environment. Familiarizing oneself with such data not only fosters workplace safety but also promotes responsible chemical usage within various industries.
